Title: Pullout spray head with pause button
Inventor: MALEK MICHAEL L
IPC: E03C1/08
Filed: 2003-09-29
Abstract: A spray head for a faucet or the like has a wand body defining a flow path from an inlet to first and second outlets. Diverter seats are provided so a face seal on a diverter spool can direct flow to the first or second outlet. The spool is positioned by a trigger acting on cam surfaces formed on a toggle. A spring biases the toggle to one of two stable states. Movement of the spool by the trigger causes the toggle to change states so subsequent actuation of the trigger causes the spool to move in the opposite direction. The wand body also has a pause button that reciprocates in a chamber that is part of the flow path. The chamber includes a valve seat and the pause button has a spool having a face seal that is engageable with the valve seat to shut off flow through the spray head. A return spring causes separation of the pause button's face seal upon release of pressure on the pause button. The pause button's seals in the chamber are arranged to have equal diameters and thus provide balanced hydraulic forces on the spool.

Abstract: This invention provides a manufacturing method of condensation reaction solution and oxidation condensation solution, filtration net and waste solution treatment thereof, which is characterized in that the concentration of a chitosan acid dipping solution is 1-10% and the solution is prepared by a ratio of water : acetic acid or other acid : chitosan or other (chemical matter-OH)n polymer : acidified or chlorinated bivalent metal ion between 97:1:1:1 and 88:4:4:4, followed by stirring for further biochemical application. Using coated activated carbon or ceramic structural chemical fiber net as a catalyst carrier, the prepared condensation reaction liquid or oxidation condensation reaction solution or other reaction liquid is added with PVP K-30 in the content of 0.1-3% or other moisture absorption agent or added with no moisture absorption agent, followed by stirring to reach homogeneity and thus exhibit deliquescence. The activated carbon or ceramic structural chemical fiber net is coated and soaked by the resultant liquid, which is followed by drying the soaked fiber net to remove water content and thus form a dry net-shaped catalyst filtration net capable of performing condensation reaction and oxidation condensation reaction or other reaction with volatile organic solvents or petroleum gases at a dry state or relative humidity above 99% to remove organic solvents and gases having similar molecular weight structure as organic solvent and other toxic gases. This condensation reaction liquid can be operated at high speed stirring to react with massive organic solvents and waste solvent agents by condensation reaction so that the organic solvents condense into colloidal solid material, which facilitates development of waste solution treatment apparatus.

Title: Lens delivery system
Inventor: BROWN KYLE
IPC: A61F2/16
Filed: 2004-02-11
Abstract: A lens delivery system having a plunger, an injector body and a nozzle portion connected to the injector body, the nozzle portion having a hinged lid and a hollow body with a lens holding platform formed beneath the hinged lid. The inside of the hinged lid contains ribs that help to hold a lens stationary on the platform when the lid is closed. The cartridge has an elongated nozzle tube or tip with a bore, the bore communicating with the lens holding platform. The bottom of the bore is rounded, which causes the edges of the lens between the lens haptics to fold upwardly as the lens is pushed down the bore from the platform by the plunger. The central portion of the optic of the lens is prevented from moving upward during folding by a projection in the lid between the ribs. A removable pin fits into the lid and prevents the lens from moving down the bore of the tip during shipment and storage. The plunger and injector body contain a ratcheting mechanism that helps prevent the plunger from moving during shipment and storage. The system of the present invention allows the lens to be stored, shipped and delivered into an eye without any additional devices and without handling the lens. The folding mechanism of the present invention is also suitable for folding lenses made from a soft acrylic material as well as other materials such as silicones and hydrogels.

Title: Methods and systems for managing security policies
Inventor: LI HONG
IPC: H04L29/06
Filed: 2004-02-12
Abstract: Methods, machines, and systems manage security policies of heterogeneous infrastructure and computing devices of a network. Security policy repository houses security policies that are pushed over the network by a policy decision point PDP to appropriate security-enabled devices (policy enforcement points (PEPs)) for enforcement. Using a closed feedback loop, a policy feedback point (PFP) collects and processes data from intrusions, alerts, violations, and other abnormal behaviors from a variety of PEPs or logs produced from PEPs. This data is sent as feedback to the policy repository. The PDP detects the data and analyzes it to determine if policy updates (which can be dynamic and automatic) need to be adaptively made and dynamically pushed to PEPs. The PDP can also send console messages or alerts to consoles or administrators.

Patent TW-200506272-A (TW)
Title: Blocking filter
Inventor: KAMEDA EIICHI
IPC: F21V9/06
Filed: 2004-05-27
Abstract: The present invention is to provide an infrared blocking filter comprising a crystal plate and a multi-layer film formed on one surface of the crystal plate. The multi-layer film is produced by inter-lacedly stacking the first thin film made of high refractivity material and the second thin film made of low refractivity material. The multi-layer film is formed by sequentially stacking the first layer, the second layer, the third layer, and so on, from one face of the crystal plate. Because the thickness of the first thin films and the second thin films of these layers is not consistent, the thickness of each layer is not the same. The thickness of layer increases sequentially. Multi-layer film is provided with the mean to avoid the sharp change of the transmissibility within the visible light bandwidth. Through the above-mentioned mean, the variant poles are formed in the transitional wavelength band corresponding to the sharp change of transmissibility.
